Diseño de un sistema bio-integrado para la gestión sostenible del recurso hídrico en proyectos acuícolas.

Abstract

This project presents the design of a bio-integrated system to improve water resource use in aquaculture projects, using the San Isidro farm in Guaduas, Cundinamarca, as a case study. Given flow limitations and previous failures in tilapia farming, sustainable alternatives based on the circular economy were evaluated. Based on an environmental and socioeconomic diagnosis, aquaponic, Biofloc, and symbiotic systems were analyzed. The solution selected through a decision matrix integrates recirculation with airlift pumping, clarification, anaerobic digestion, and the use of organic ferments, allowing for reduced waste, nutrient reuse, and the production of biofertilizers. Hydraulic units were sized, water quality parameters were established, monitoring methods were defined, and a financial analysis was conducted. The results indicate a significant improvement in water efficiency, reduced environmental impacts, and economic viability with returns of 25% in the scenarios evaluated. This proposal seeks to strengthen aquaculture sustainability in rural areas with limited access to water, contributing to responsible and circular production models.
